... data is used, the cascaded model outperforms the interpolated model for some recall values, and vice versa, while both models dominate the supervised approach for the full range of recall values. As ... coarse-grained model only performs well on the predominant sentence-level categories for each docu- ment category. The supervised model handles nega- tive and neutral sentences well, but...

Although neither SCF nor CO performs well on its own, a combination of them proves to be the most in- formative feature for this task. ... 10 verbs. We therefore reduce the number of training verbs to 9 for each class. For each n = 2, 5, 10, 20, 30, 40, 48, we will perform certain number of n-way classification tasks. For e...
